Detailed Description
(example 1)
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Fig. 1 is a schematic diagram of a main part structure of a drum-type washing machine (washing machine) 10 according to embodiment 1. The drum-type washing machine 10 includes a main body 100 and a door 120, and has a washing tub 110 on the main body 100 side, and the washing tub 110 includes a rotary drum 111 therein. The washing tub 110 is open at the front side of the body 100, and the inside thereof is liquid-tightly sealed when the door 120 is closed.
The filter unit 20 is connected to the washing tank 110 via a first pipe 131 and a second pipe 132. Further, a circulation pump 140 is provided in the middle of the second pipe 132. That is, a circulation passage constituted by the first pipe 131, the second pipe 132, the filter unit 20, and the circulation pump 140 is provided outside the washing tank 110, and washing water is circulated between the washing tank 110 and the circulation passage during washing. Specifically, the washing water is sent from the washing tank 110 to the filter unit 20 through the first pipe 131, and returned from the filter unit 20 to the washing tank 110 through the second pipe 132. At this time, the waste such as lint generated during washing is collected by the filter in the filter unit 20, and the washing water from which the waste is removed is returned to the washing tub 110. Although second pipe 132 is connected to the back side of washing tub 110 in fig. 1, the position of connection of second pipe 132 to washing tub 110 is not particularly limited.
A third pipe 133 for drainage is also connected to the filter unit 20, the circulation pump 140 is connected to the second pipe 132, and the solenoid valve 151 is provided in the third pipe (drainage pipe) 133. That is, during washing, the electromagnetic valve 151 on the third pipe 133 side is closed, and the circulation pump 140 on the second pipe 132 side is operated to circulate the washing water. At the time of draining, the circulation pump 140 is stopped and the electromagnetic valve 151 is opened, whereby the water can be drained from the washing tub 100.
Next, a specific configuration of the filter unit 20 according to embodiment 1 will be described. Fig. 2 is an exploded perspective view of the filter unit 20 viewed from diagonally above and forward, and fig. 3 is an exploded perspective view of the filter unit 20 viewed from diagonally above and rearward.
The filter unit 20 is composed of a filter case 21, a lint filter (filter) 30, and a knob member 22. The filter case 21 is a bottomed cylindrical case member, and houses the lint filter 30 therein. The filter housing 21 is disposed in the drum-type washing machine 10 such that the longitudinal axis of the drum portion is oriented in the front-rear direction. In the following description, the orientation of the filter unit 20 is the arrangement orientation in the drum-type washing machine 10, the front side corresponds to the front side of the drum-type washing machine 10, and the rear side corresponds to the rear side of the drum-type washing machine 10.
An insertion port 211 into which the lint filter 30 is inserted is provided on the front side of the filter case 21, and the lint filter 30 is detachable from the filter case 21 through the insertion port 211. More specifically, the lint filter 30 is attached to and detached from the filter case 21 in a state of being attached to the knob member 22. At this time, the front end of the lint filter 30 is inserted into the rear end of the knob member 22, and the lint filter 30 is attached to the knob member 22. The knob member 22 is provided with an external thread portion 221, and the insertion port 211 of the filter housing 21 is provided with an internal thread portion 212, so that the lint filter 30 can be attached to and detached from the filter housing 21 by rotating the knob member 22.
An inlet 213, an outlet (second outlet) 214, and a drain (first outlet) 215 are formed on the side surface of the cylindrical portion of the filter case 21. The inlet 213 is provided above the filter case 21 and connected to the first pipe 131. The outlet 214 is connected to the second pipe 132, and the drain 215 is connected to the third pipe 133. The lint filter 30 in the filter case 21 is disposed between the inflow port 213 and the outflow port 214 and the drain port 215. Thus, the lint filter 30 can perform a filter function for the washing water (circulating water) flowing from the inlet 213 to the outlet 214 during washing, and can perform a filter function for the washing water (drain water) flowing from the inlet 213 to the drain 215 during draining.
Fig. 4 is a perspective view showing a specific configuration of the lint filter 30 according to example 1, where (a) shows a state of being housed in the filter case 21, and (b) shows a state of being detached from the filter case 21 and removing the accumulated dust.
The lint filter 30 is constituted by a filter main body 31 and a movable member 32. Fig. 5 (a) is a perspective view of the filter main body 31, and fig. 5 (b) is a perspective view of the movable member 32. The filter body 31 is composed of a base portion 311 into which the knob member 22 is inserted, and a filter portion 312 extending rearward from the base portion 311. The filter portion 312 is a bottomed filter portion having an upper opening, and at least side surfaces and a rear surface are filter surfaces. Specifically, the bottom surface of the filter unit 312 is a lattice filter, and the side surfaces and the rear surface are rib-shaped filters each including a plurality of ribs extending in parallel to the vertical direction (vertical direction). In the filter unit 312, a filter surface formed with ribs is provided toward the outlet 214 and the drain port 215, and is provided with an opening toward the inlet 213.
The movable member 32 is fitted into the filter unit 312 from above, and is slidable in the vertical direction along the filtering surface of the filter unit 312 (more specifically, along the side and rear ribs of the filter unit 312). Therefore, a plurality of grooves (or holes) are formed at the periphery of the movable member 32 to engage with the ribs of the filter portion 312. In a state where the lint filter 30 is accommodated in the filter case 21, as shown in fig. 4 (a), the movable member 32 is pushed down to be in contact with the bottom surface of the filter portion 312.
The washing water flowing in from the inlet 213 of the filter case 21 in the filter unit 20 during use (during washing or draining) flows in from above the filter unit 312, passes through the filter surface (bottom surface, side surface, and rear surface) of the filter unit 312, and flows out from the outlet 214 or the drain 215 of the filter case 21. At this time, waste such as lint mixed in the washing water is collected by the filtering surface of the filter unit 312. In addition, the collected trash accumulates on the upper face side of the movable member 32.
In the case of removing the dust accumulated in the filter unit 20, the lint filter 30 is drawn out of the filter case 21, and the movable member 32 is pulled upward as shown in fig. 4 (b). At this time, in the movable member 32, the portion provided between the ribs of the filter section 312 serves as a guide portion that guides the movement along the ribs of the filter section 312. Since the trash collected by the lint filter 30 is accumulated on the upper surface side of the movable member 32, the trash such as lint attached to the ribs of the filter portion 312 can be scraped off and collected by the action of pulling up the movable member 32, and the trash can be easily removed from the lint filter 30 only by turning over the lint filter 30. At this time, the user does not need to contact the trash accumulated on the lint filter 30 in the action of pulling up the movable member 32.
That is, the guide portion provided between the ribs of the filter portion 312 in the movable member 32 of the lint filter 30 can remove the dust between the ribs by moving along the ribs. In addition, the guide portion is provided between the ribs, so that deformation, falling-off, and the like of the movable member 32 are suppressed. The movable member 32 preferably has a handle portion 321 protruding outward from the side surface of the filter portion 312. By providing the handle portion 321 on the movable member 32, the user can easily move the movable member 32.
In the above description, the case where the lint filter 30 is constituted by the filter main body 31 and the movable member 32 is exemplified. However, the present invention is not limited to this, and instead of the movable member 32, a movable member 33 shown in fig. 5 (c) and a movable member 34 shown in fig. 5 (d) may be used.
The movable member 32 shown in fig. 5 (b) itself has no filtering surface. In contrast, the movable member 33 shown in fig. 5 (c) itself has a filter surface. Thus, the movable member 33 does not destroy the filter function of the lattice filter on the bottom surface of the filter unit 312 of the filter main body 31.
The movable member 32 has an outer frame 322 around its periphery, and each of the ribs on the side and rear surfaces of the filter main body 31 has an engagement projection 313 whose tip projects outward. In this configuration, as shown in fig. 4 (b), when the movable member 32 is pulled upward, the outer frame portion 322 of the movable member 32 is caught by the engaging projection 313, and the movable member 32 can be prevented from falling off from the filter main body 31. On the other hand, the movable member 34 shown in fig. 5 (d) is configured without an outer frame portion around the movable member 34 so that the movable member 34 can be easily extracted from the filter main body 31. In this configuration, the removal of the dust accumulated in the lint filter 30 can be further ensured by the operation of pulling the movable member 34 out of the filter main body 31.
Further, the lint filter 30 according to embodiment 1 may be composed of a filter main body 35 and a movable member 36 shown in fig. 6 (a) and (b). In the lint filter 30 shown in fig. 6 (a) and (b), the engagement projections from the front ends of the ribs on the side surface and the rear surface are removed from the filter main body 35. Even in this configuration, the movable member 36 can be easily drawn out from the filter main body 35.
(example 2)
Hereinafter, in example 2, a structure of a lint filter different from that of example 1 will be described. Fig. 7 is a perspective view showing a specific configuration of the lint filter 40 according to example 2, where (a) shows a state of being housed in the filter case 21, and (b) shows a state of being detached from the filter case 21 and removing the accumulated dust. In embodiment 2, the lint filter 40 is used in place of the lint filter 30 in embodiment 1, but the same member as in embodiment 1 may be used for the filter case 21 and the knob member 22.
The lint filter 40 according to embodiment 2 is composed of a filter main body 41 and a movable member 42. Fig. 8 (a) is a perspective view of the filter main body 41, and fig. 8 (b) is a perspective view of the movable member 42. The filter body 41 is composed of a base 411 into which the knob member 22 is inserted, and a filter part 412 extending rearward from the base 411. The filter part 412 is a bottomed filter part having an upper opening, and at least side surfaces and a rear surface are filter surfaces. Specifically, the bottom surface of the filter unit 412 is a lattice filter, and the side surfaces and the rear surface are rib-shaped filters each formed of a plurality of ribs extending in parallel to the vertical direction. However, the side ribs extend substantially vertically, and are formed in a concentric circle shape with respect to a pivot point a described later.
The movable member 42 is fitted into the filter portion 412 from above, and has rotation protrusions 421 on both side surfaces of a front end portion of the movable member 42. On the other hand, the filter body 41 has a rotation hole 413 for fitting the rotation protrusion 421. When the movable member 42 is fitted into the filter portion 412, the rotation protrusion 421 is fitted into the rotation hole 413 to serve as a rotation fulcrum a, and the movable member 42 is rotatable in the vertical direction around the rotation fulcrum a and along the filtering surface of the filter portion 412 (more specifically, along the side surface and the rear surface of the filter portion 412). In a state where the lint filter 40 is accommodated in the filter case 21, as shown in fig. 7 (a), the movable member 42 is pushed down to be in contact with the bottom surface of the filter portion 412.
At this time, in the lint filter 40 according to example 2, the waste such as lint mixed in the washing water is also collected by the filtering surface of the filter portion 412, and the collected waste is accumulated on the upper surface side of the movable member 42.
When the dust accumulated in the filter unit 20 is removed, the lint filter 40 is drawn out of the filter case 21, and the movable member 42 is rotated upward as shown in fig. 7 (b). At this time, in the movable member 42, the portion provided between the ribs of the filter portion 412 serves as a guide portion that guides the movement along the ribs of the filter portion 412. Since the trash collected by the lint filter 40 is accumulated on the upper surface side of the movable member 42, the trash such as lint attached to the ribs of the filter portion 412 can be scraped off and collected by the upward rotation of the movable member 42, and the trash can be easily removed from the lint filter 40 by merely turning over the lint filter 40. At this time, the user does not need to contact the trash accumulated on the lint filter 40 in the action of rotating the movable member 42.
In the lint filter 40 according to embodiment 2, since the movable member 42 is moved while being rotated about the rotation fulcrum a, the amount of movement is large at a position distant from the rotation fulcrum a (i.e., near the rear end), and is small at a position close to the rotation fulcrum a (i.e., near the front end). On the other hand, in the filter case 21, the outlet port 214 is provided near the middle portion in the front-rear direction, and the drain port 215 is provided near the rear end portion. Therefore, the dust collected by the filter unit 412 is almost accumulated from the middle portion to the vicinity of the rear end portion of the filter unit 412, and if the amount of movement of the movable member 42 becomes large in the vicinity of the rear end portion, the dust can be easily removed.
In the above description, the case where the lint filter 40 is constituted by the filter main body 41 and the movable member 42 is exemplified. However, the present invention is not limited to this, and the movable member 43 shown in fig. 8 (c) may be used instead of the movable member 42.
The movable member 42 shown in fig. 8 (b) itself has no filtering surface. In contrast, the movable member 43 shown in fig. 8 (c) itself has a filter surface. Thus, the movable member 43 does not destroy the filter function of the lattice filter on the bottom surface of the filter part 412 of the filter main body 41.
Further, the lint filter 40 according to embodiment 2 may be composed of a filter main body 44 shown in fig. 9 (a) and a movable member 45 shown in fig. 9 (b). The movable member 45 has lever portions 452 on both side surfaces of a front end portion, and a pivot projection 451 is provided on the lever portion 452. On the other hand, the filter body 44 has a rotation hole 443 for fitting the rotation projection 451. When the movable member 45 is fitted into the filter body 44, the pivot protrusion 451 is fitted into the pivot hole 443 to form a pivot point a. In this configuration, the fitting state of the pivot projection 451 and the pivot hole 443 can be released by pushing the lever portion 452 inward, and the movable member 452 can be easily pulled out from the filter main body 44. Then, by the action of drawing the movable member 45 out of the filter main body 44, it is possible to further ensure the removal of the trash accumulated in the lint filter 40.
(example 3)
In example 3, a structure of a lint filter different from those in examples 1 and 2 will be described. Fig. 10 is a perspective view showing a specific configuration of the lint filter 50 according to example 3, where (a) shows a state of being housed in the filter case 21, and (b) shows a state of being detached from the filter case 21 and removing the accumulated dust. In embodiment 3, although the lint filter 50 is used instead of the lint filter 30 in embodiment 1, the same member as in embodiment 1 may be used for the filter case 21 and the knob member 22.
The lint filter 50 according to embodiment 3 is composed of a filter main body 51 and a movable member 52. The lint filter 50 shown in fig. 10 is shown as a modification of the lint filter 30 shown in fig. 6.
The filter body 51 has a side surface and a rear filtering surface, and is not only a rib-shaped filter including a plurality of ribs extending in the vertical direction, but also a plurality of collecting ribs 511 provided inside the filtering surface in the vicinity of the rear end.
As also described in example 2, the trash collected by the filter portion of the lint filter is almost accumulated from the center portion to the vicinity of the rear end portion of the filter portion. The collected dust stays only near the rear end of the collecting rib 511 of the filter main body 51, and the collected dust has a function of reducing the dust accumulated near the center of the filter unit. This prevents the outflow port 214 of the filter housing 21 from being clogged with the accumulated dirt and blocking the circulation of the washing water, particularly during washing of the drum-type washing machine 10.
(example 4)
In example 4, the structure of a lint filter different from those in examples 1 to 3 will be described. Fig. 11 is a perspective view showing a specific configuration of the lint filter 60 according to example 4, where (a) shows a state of being housed in the filter case 21, and (b) shows a state of being detached from the filter case 21 and removing the accumulated dust. In embodiment 4, although the lint filter 60 is used instead of the lint filter 30 in embodiment 1, the same member as in embodiment 1 may be used for the filter case 21 and the knob member 22.
The lint filter 60 according to embodiment 4 is composed of a filter main body 61, a movable member 62, and an opening/closing member 63. The filter portion 611 of the filter main body 61 is a bottomed filter portion having upper and rear openings, and at least side surfaces thereof are filter surfaces. Specifically, the filter surface of the filter portion 611 is a rib-shaped filter including a plurality of ribs extending in the front-rear direction (horizontal direction).
The movable member 62 can be fitted into the filter portion 611 from the rear, and the ribs along the side of the filter portion 611 can slide in parallel with the front-rear direction. In a state where the lint filter 60 is housed in the filter case 21, as shown in fig. 11 (a), the movable member 62 is positioned on the front side with respect to the filter portion 611.
The opening/closing member 63 is attached to the rear end of the filter unit 611, and opens and closes the rear end of the filter unit 611. In a state where the lint filter 60 is housed in the filter case 21, as shown in fig. 11 (a), the opening/closing member 63 closes the rear end portion of the filter unit 611. Although the opening/closing member 63 itself has a filter surface in fig. 11, the opening/closing member 63 may not have a filter surface.
The washing water flowing in from the inlet 213 of the filter case 21 in the filter unit 20 during use (during washing or draining) flows in from above the filter portion 611, passes through the filter surface of the filter 611 (or the filter surface of the opening/closing member 63), and flows out from the outlet 214 or the drain port 215 of the filter case 21. At this time, the waste such as lint mixed in the washing water is collected by the filtering surface of the filter unit 611 (or the filtering surface of the opening/closing member 63). In addition, the collected garbage accumulates on the rear side of the movable member 62.
When removing the dust accumulated in the filter unit 20, the lint filter 60 is pulled out from the filter case 21, and as shown in fig. 11 (b), the opening/closing member 63 is opened to move the movable member 62 rearward along the filtering surface of the filter portion 611 (more specifically, along the ribs on the side surface of the filter portion 611). Since the dust collected by the lint filter 60 is accumulated on the rear side of the movable member 62, the dust such as lint attached to the ribs of the filter portion 611 can be scraped off and collected by the movement of moving the movable member 62 from the front to the rear, and the dust can be easily removed from the lint filter 60 only by directing the rear end portion of the lint filter 60 downward. At this time, in the movable member 62, the portion provided between the ribs of the filter portion 611 becomes a guide portion that guides the movement along the ribs of the filter portion 611. The user does not need to contact the trash accumulated on the lint filter 60 in the action of rotating the movable member 62.
Although not shown in fig. 11, the movable member 62 may be provided with a handle portion protruding outward from the filtering surface of the filter portion 61. Such a handle portion may be provided at a rear surface of the movable member 62 (after the movable member 62 is attached to the filter body 61, the handle portion is attached to the movable member 62 from the outside of the filter surface). In this case, the movable member 62 is easily moved by the handle portion, and the ribs of the filter portion 611 can be reinforced.

In embodiments 1 to 4 described above, the movable member is provided as an integral member composed of one member, and such an integral member can be formed of resin. However, in particular, if the movable members 32, 36, 42, 52, 62 do not have a filter surface, they may be a member in which two members are combined.
Taking the movable member 42 as an example, as shown in fig. 12 (a), the movable member 42 can be constituted by a base member 42A and a lid member 42B covering the base member 42A. Further, taking the movable member 62 as an example, as shown in fig. 12 (B), the movable member 62 may be constituted by a base member 62A and a lid member 62B covering the base member 62A. In this case, the base member 42A or 62A and the lid member 42B or 62B can be made of different materials. For example, the base member 42A or 62A can be formed of resin, and the lid member 42B or 62B can be formed of rubber. By forming the cover member 42B or 62B as rubber so that the groove portion engaging with the rib of the filter portion 412 or 611 is brought into close contact with the rib, it also becomes easy to scrape off the trash adhering to the rib. In addition, in the combination of different materials, in addition to the combination of 2 members, it is also considered to cope with the shape of the scraping portion as a 2-color rubber molded product.
In addition, in the above-described embodiments 1 to 4, the movable member needs not to be moved to the predetermined initial position in the state where the lint filter is accommodated in the filter case 21. However, there is considered a case where after the user moves the movable member for removing the dust from the lint filter, the user forgets to return the movable member to the original initial position and mounts the lint filter on the filter housing 21.
In contrast, it is considered that the lint filter cannot be accommodated in the filter case 21 in a state where the movable member is not returned to the initial position. As a specific example, the lint filter 30 shown in fig. 4 can be considered as having the following configuration (see fig. 13 (a)): a restricting portion 216 projecting in a brush shape is provided on the inner wall of the filter case 21, and in a state where the movable member 32 is not returned to the initial position (for example, in a state of fig. 4 (b)), the handle portion 321 of the movable member 32 (i.e., a portion projecting outward from the side surface of the filter portion 312) abuts against the restricting portion 216, and the lint filter 30 cannot be inserted into the filter case 21. In this case, in a state where the movable member 32 is not returned to the initial position (fig. 4 (a)), the handle portion 321 can be inserted into the filter case 21 without abutting against the restricting portion 216 (see fig. 13 (b)).
In the lint filter 60 shown in fig. 11, the movable member 62 may be returned to the initial position by interlocking the movement of the lint filter when the lint filter is inserted into the filter case 21, if the movement direction of the movable member 62 is the same as the insertion direction of the lint filter when the lint filter is inserted into the filter case 21. For example, as shown in fig. 14, (see fig. 14 (b)), a protruding restricting portion 217 is provided inside the filter housing 21, and when the lint filter 60 is inserted into the filter housing 21, the movable member 62 abuts against the restricting portion 217 to restrict the movement thereof, and the movable member 62 returns to the initial position. Even with this configuration, the lint filter 60 can be prevented from being attached to the filter case 21 in a state where the movable member 62 is forgotten to return to the original initial position.
